And how would I do that? What I've done until now, is sort by query function, with increasing boosts, eg: sort=query({!v=id:(1^1 OR 2^2 OR 3^3 OR 4^4 OR............ )})+asc
But this isn't very performant. When using +-7000 id's it will take about a minute for Solr to find results. I'm actually looking for a more effencient way. -- View this message in context: http://lucene.472066.n3.nabble.com/Solr-sort-by-fixed-id-list-tp4156854p4156888.html Sent from the Solr - User mailing list archive at Nabble.com.
